filebeat写入ES修改index

开始按照网络说法，修改

output.elasticsearch.index: "test"

启动filebeat报错，406

后参考官网：https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-template.html

example:

output.elasticsearch.index: "customname-%{[beat.version]}-%{+yyyy.MM.dd}"
setup.template.name: "customname"
setup.template.pattern: "customname-*"

成功
